I TANK CONSTRUCTION Filed Feb. 8, 1928 2 Sheets-Sheet 2 Patented Dec. 3, 1929 UNITED STATES ROLLAND .rosnrn cAznLLn, or MONTREAL, ounnnc, can Ann TANK oons'rauc'rron Application filed February 8, 1928, Serial No. 252,810, and in Canada Karch4, '1927( will be simple and cheap of construction and I so constructed that easy access will be had to the electrical connections, and heating units.

The invention is hereinafter fully described in the following specification and illustrated in the accompanying drawings, in which:

Figure 1 is a longitudinal sectional view through a water heating tank according to the invention.

* I Figure 2 is an enlarged segmentarry longitudinal sectional view through a slightly modified form of the invention.

Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawlngs, 1 is the main water tank, provided with the usual water inlet pipe 2, and the hot water outlet pipe 3 which is about one inch longer, at the top of 80 the tank 1 than the said inlet pipe 2, and die the return pipe. 5 are the heating unit casings connected to the cold water inlet supply pipe 2, and to the inlet pipe 2 which projects into said water tank 1. in each of said heat- $5 ing unit casings 5 isplaced an inner casing carrying its heating element 6. 'Z is an intermediate or central superposed casing or tank, the inner side of which is nickel piated to refleet the heat rays back on the main water tank i, and 8 is a frame upon which is suit ably secured the said central. tank 7, also supporting the main water tank 1, said frame 8 being also supported and secured to the main frame Qwhich is provided with the standards '10. On said main frame 9 is mounted the outer superposed open end casing 11, the inner side of said casing being lined with galvanized tin. 12., The main object is to strengthen same, and keep the outer. cold air from reaching said main tank 1. Each pf said superposed tanks are preferably spaced from one another as disclosed in the drawlngs.

The water tank'l is insulated from the center tank 7 by a lining 13 of asbestos or the like, and 13 is another asbestos lining provided to insulate the frame 9 from said center tank. The main object in providing these asbestos linings 13 and 13, is to prevent the cold air from reaching the bottom of said 0 main water tank 1.. The frame 9 is provided with an agron 14 which encloses the. heating units 5. n the apron l4,is provided an opening 15 through which'passes the hot water pipe 3, and 16 is'a tap valve connected as on the outer end of said pipe.

It will be-readily seen with the aid of the present description and drawings,-that the tank is of simple construction and that if the heating elements should burn out, easy access may be had to said heating elements without disconnecting the water connections, and consequently, the cost of repairing same is reduced to a minimum. I also wish to make it clearly understood, that modifications may be made in the construction of said tank, providing they fall within the scope of the following claims for novelty.

What I claim as my invention is:

l. A- water tank of the character described, so comprising a main'tank, an inlet and outlet pipe connected thereto, an intermediate tank enclosing said main tank and suitably distanced therefrom, means on the inner surface of said intermediate tank to reflect the heat ra s radiating from said main tank, an inen ating lining located between the bottoms of said tanks, a frame for supporting said tanks, an insulating linin located between said intermediate tank an said frame, and an outer open and superposed casing enciosing said intermediate tank, suitably distanced therefrom and supported upon said frame, substantially as described. 7

2. A hot water tank comprising a rnain tank, an intermediate tank enclosing said main tank and suitably distanced therefrom, means on the inner surface of said intermediate tank to reflect the heat rays radiating from said main tank, an insulating member.

located between the bottoms of said tanks, and an. outer super w casin'f enclosinei said intermediate I r and suitab y distanc therefrom.

3. A hot water tank comprising a main tank, a casing surrounding said tank, the inner surface of said casing having a surface ada ted to reflect heat rays radiating from sai tank, and a heat insulating member between the bottom'of said casing and the bottom of said tank. 1
